Not sure what you mean, but... As you said, it's a 4++ year old server, it's normal that there are almost no people on low level location - moreover, most people level through early levels via raid parties, so there isn't really anything to do in those low lvl farming zones in a first place - you're supposed to either wait for an RB party or make RB party yourself when you see alive RB (you can check what's alive through the map window). The farming locations are mostly to kill time while waiting for the RB... The population is pretty damn good, it's just that most people are 70+...
